Abstract

Une table de recherche sensible à un ou plusieurs états de fonctionnement d'un circuit électrique permet de régler de façon dynamique l'alimentation variable d'un amplificateur dans ce même circuit électrique. Cette table de recherche est sensible à un ou plusieurs états de fonctionnement et permet de déterminer le niveau d'amplification que l'amplificateur doit appliquer au signal d'entrée. Un premier mode de réalisation comprend un circuit d'émetteur de télévision qui comporte un circuit d'amplificateur de puissance capable d'amplifier un signal d'entrée COFDM ou 8VSB à fréquence variable, et dans lequel le niveau d'amplification appliqué au signal d'entrée est réglé de façon dynamique au moyen d'une table de recherche en fonction de la fréquence du signal d'entrée.
